SPUR.

SPECIFICATION forming part of Letters Patent N 0. 729,791, dated June 2, 1903.

Application filed May 6, 1902. Serial No. 106,212. (No model.) i h To all, whom it may concern:

Be it known that I, WALTER OLMSTEAD, a citizen of the United States, residing at Beefcreek, in Chickasaw Nation, Indian Territory, have invented a new and useful Spur, of which the following is a specification.

The invention relates to improvements in spurs.

The object of the present invention is to improve the construction of spurs, more es pecially the manner of mounting the rowel, and to provide a simple and inexpensive spur provided with arowel having a limited rotary movement and adapted when at the limit of its movement to enable a rider to clamp with his legs a horse without liability of the spurs slipping 011 the same, as is the case when an ordinary rotary rowel is used.

A further object of the invention is to increase the strength of the means for attaching the rowel and to prevent the same from becoming lost when the pivot wears out.

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

111 the drawings, Figure l is a side elevation of a spur constructed in accordance with this invention. Fig. 2 is a plan view.

Like numerals of reference designate corresponding parts in all the figures of the drawings;

1 designates a spur-frame, which may be of any desired construction and which is provided with a rearwardly=extendin g rowel stud or shank 2, upon which is mounted a rowel The rowel stud or shank, which may be of any desired construction, is preferably provided with a slot or bifurcation for the reception of the rowel 3. The rowel 3, which is capable of a limited rotary movement, is mounted on a pivot 4, and is provided at its periphery with teeth 5, extending about twothirds of the distance around the rowel and arranged at the back, top, and bottom of the same. The front portion 6 of the periphery of the rowel is smooth and does not come in contact with an animal. The pivot at preferably consists of a rivet which extends across the slot or bifurcation of the rowel shank or stud, and the rowel is also connected with the shank or stud by means of a transverse fastening device 7, mounted on the shank or stud and passing through a curved slot or opening 8.

the spur from slipping, and the said spur may 7 be used to prevent arider from falling oif a horse and can be engaged with the cinchplate or buckle or with the sides of the animal for this purpose.

The pivot onwhich therowel rotates receives the greater wear, and the: fastening device, which'passes through the slot, receives ver Y little wear, so that when the pivot is worn through and becomes broken the fastening device 7 will prevent the rowel, which would otherwise become lost, from leaving the shank or stud. Owing to the unequal wear on the rivets, both cannot become worn out at the same time and the rowel cannot become lost. The sides of the spur-frame are provided with upwardly-extending ears or portions 9, designed to be attached to a strap and adapted to hold the spur up and prevent the same from dropping too low on the heel of a boot.

It will be seen that the spur is simple and comparatively inexpensive in construction, that the strength and durability of the rowel are increased, and that the means which limit the movement of the rowel to prevent the same from slipping or to serve to prevent the rowel from becoming lost should the pivot wear out or break. Furthermore, it will be clear that as the smooth portion 6 of the pe= riphery of the rowel lies in the opening or bifurcation of the rowel stud or shank and the teeth or projections 5 are located at points remote from the said shank or stud there is no liability of the teeth or projectionsaccidentally catching in the "stud or shank and interfering with the rotation and operation of the rowel, as is the-case with rowels of the ordinary construction when they become loose and move transversely in the slot or bifurca= tion. Any transverse movement in the slot or bifurcation of a rowel, provided throughout its entire periphery with teeth or projections, will cause such teeth or projections to catch on the edges of the shank or stud, whereby the rowel will be prevented from-rotating.

WVhat I claim is- 1. A spur provided with a rotary rowel and having means for limiting the rotary movement of the rowel, whereby the said rowel is capable of a limited rotary movement to permit the spur to be operated in the ordinary .manner and is-prevented from slipping at the limited rotary movement and provided adjacent to its support with a smooth peripheral portion, whereby the rowel is prevented from catching on its support, substantially as and for the purpose described.

5. A spur comprising a frame having a rowel stud or shank, a rowel pivoted to the stud or shank and provided at its periphery with teeth or projections arranged at points remote from the stud or shank, said rowel being provided adjacent to the shank or stud with a smooth peripheral portion to prevent it from catching on the same, and means for limiting the rotary movement of the rowel, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
